Another Small Step Forward.

I received 8 aluminum bulk plates from a rocketry friend back in Idaho. These were cut on a water jet, which left the edges rather rough. A coworker offered to make me a arbor to mount the plates on so I could easily sand/file the plates to size and keep them round. Works like gang busters! Thanks to both Dave and Michael for helping me move my rocket forward.

Two of the bulk plates. The one on the left is the unfinished edge produced by the water jet. The one on the right has been sanded using the arbor.
